I am a complete noob when it comes to apple computers but i am very tired of Microsoft so i decided to give it a shot especially with the price cuts. I know this question has probably been asked several times but i really need some help on deciding which one to buy. I am torn between buy the 13: 2.5GH processor and 4GB RAM 320GB HD or should i just save a llittle bit of money and just go with the lower end MBP but upgrade to 500MB? See I am a college student but am also in the military and go off on trips alot and because i am away from my family so much i do alot of photo editing and video editing to keep in touch. i know upgrades i can do myself but im leaving very soon and wont have time to upgrade it myself so please help me out.
